Garbage app
Terrible. It’s been a problem for quite some time now but YouTube/Google doesn’t care enough to fix it. What I mean is - after answering a text message from the notification the app freezes, with the picture not responding, touch screen frozen but the sound still playing. Only after pressing the lock button the screen goes slightyl darker (still unresponsive) and then locks. After that each message you answer while playing a video will freeze the app in the same way. You can’t force it to quit while it’s frozen. The only thing you can do is try to lock it and wait... and wait...
